Unfortunately I've reinstalled .NET at least three times and the VC redistributable twice :(

Backup your controls key settings then delete all config files from both Il-2 folders (Steam and Documents). Run integrity check to download new config files.

Try editing conf.ini to reduce resolution and run in a window as a test.

Done the delete-and-revalidate. No difference.

Regarding screen res, which of the various conf files in different locations (which takes precedence?) contains those lines and (if they are not present) what should they look like?

Thanks!

same problem
 

I have the same problem :/
my pc specs are:

nVidia GeForce GTX580 1536MB GDDR5 RAM
Intel® Core™ i7-2600K 4x3.40GHz (Turbo 3.80GHz)
Kingston HyperX 8GB DDR3-1600 RAM

It's allmost brand new and running BF3 perfect on max settings :)
but i would LOVE to start really dogfighting ;)

Had friend with a similar problem. I asked him to check his page file and he did, it was quite a bit lower than it should have been, he adjusted it to properly match his ram and it solved his problem.

I have also read in a post in the past about adjusting cache size. Not sure if that would help.
